This study determined the specificity of cardiovascular endurance training on a bicycle ergometer. Eighteen male subjects were tested on a heart rate response test of 150 beats per minute on a bicycle ergometer at the pace of 50 revolutions per minute (rpm) and at 160 beats per minute at 60 and 80 rpm, with the resistance equal to the force of gravity of three kilograms. The subjects were then randomly divided into three training groups, each group to train at one of three initial testing paces. All three groups significantly improved performance on all three performance tests to the .01 level of confidence. No significant differences were found among the groups on any of three performance tests. It was concluded that, within the limitations of this study, pace training appears to be general rather than specific with regard to cardiovascular endurance training. (Authors/JA)
